At the edge of Earth's magnetic field, satellites have found X-shaped fields and fast-moving "islands" of magnetism that could shed light on the physics of solar storms.
The decades-old theory of the layers of the Earth's ionosphere, which dates to 1931, has just received an update that takes into account the angle of the Sun.
Researchers could launch an electron beam device into space to study the Earth's magnetic field and trigger artificial auroras and lightning.
Tons of cosmic dust enter Earth’s atmosphere each day, triggering a range of phenomena that scientists are only just beginning to understand.
An updated analytical technique gave researchers a new look at ion cyclotron waves in Mars’s extended hydrogen exosphere.
Scientists attempting to understand the Earth’s exosphere use a spectrometer to study different types of hydrogen atoms energized by the sun.
